Oxidative stress and haematological profiles of goats reared under different management systems
2018
Adenkola, A. Y. | Adah, A. S. | Azeez, O. M.
This study was done to assess oxidative stress and haematologicalparameters of twenty male goats aged between eight and 22 months of the West African Dwarf breed reared under twomanagement systems. Ten bucks were reared under an intensive system, and another 10 bucks reared under an extensivesystem were used. The Hb concentration obtained in both groups was significantly (p<0.05) higher in the intensively managedgoats (12.39±0.02 gm %) compared to the extensively managed group. The total erythrocyte count in intensive goats, 35.34±1.36×106/μl, was significantly (p<0.05) higher than the value recorded in the extensive group (30.01±1.41×106/μl). Therecorded leucocytes counts in intensive goats of 10.26±0.70×103/μl was significantly (p<0.05) lower than 12.38±1.23×103/μlrecorded in the extensively managed goat, while the calculated value of MCV in intensive goat (9.8±0.73 fl) was significantly(p<0.05) higher than the recorded value in extensive group. The obtained value of MCH was significantly higher (p<0.05) in theextensively managed goats. The recorded neutrophil value of 5.00±0.50×103/μl in extensively raised goats was significantly(p<0.05) higher than 3.70±0.20×103/μl obtained in the intensively raised group likewise the lymphocyte count of 5.60±0.08 ×103/μl in intensively raised goats was significantly (p<0.05) lower than the value obtained in the extensively raised goat. The neutrophil:lymphocyte ratio was significantly higher (p<0.05) in the extensive versus the intensive group viz. 0.75±0.03 asagainst 0.67±0.04. In the extensive group a higher malondialdehyde (MDA) value of 2.30±0.07 ng/ml was recorded and this was significantly (p<0.05) higher than the corresponding value of 1.28±0.11 ng/ml obtained in the intensively managed goats. The recorded value of superoxide dismutase, catalase and glutathione peroxidase was significantly (p<0.05) higher in theextensive group than those on the intensive group. The fragility test of the extensively managed goats shifts more towards rightand was significantly (p<0.05) highest at a sodium chloride concentration of 0.2-0.7% in extensively managed goats. It can beconcluded from the present study that the biomarkers of oxidative stress were higher in the extensively than the intensively managed goats.

Identification of processed animal protein in animal feedstuffs wasperformed under the feed safety programme to ensure that the products used locally to feed the livestock are safe and properly labeled to prevent unnecessary incidence that will affect both animal and human.A “silica-membrane technology” method was applied based on its fast and effective purification of nucleic acids from various matrices. The silica membranes were optimized for high DNA recovery and lowbinding efficiency for impurities. Results from 58 with various kinds of samples showed negative of unwanted processed animal protein.

2011
Suhaimi D. | Lily Suhaida M. S. | Ismail M. | Wan Syahidah H.
A monitoring program for melamine in milk and feed was conducted in response to global melamine alertness in the year 2008. Two screening methods were adopted i.e., a liquid chromatography triple quadrupole tandem mass spectrometry (LC-MS/MS) and enzyme-linked
immunosorbent assay (ELISA). The liquid chromatography method developed by several international research centers was adapted. This method consisted of an initial extraction with 10%trichloroacetic acid (TCA) for milk samples or 60% methanol/water for feed samples, followed by a series of centrifugation, dilution and filtration steps. Melamine was analysed in the chromatographic program using a zwitterionic HILIC LC column. Electrospray ionisation in positive ion mode was used. The quantity of melamine
present was determined with a calibration curve consisting of sample extracts from milk or feed fortified from 25 to 50 ppb that were taken through the extraction procedure. The ranges of recovery from
fortified raw milk samples (n=20) and feed samples (n=21) was 70–80% and 68%, respectively. The limit of detection was estimated at 10 ppb for both matrixes. Milk samples were found negative for melamine,
however 4.5% of feed samples were found to contain the compound at concentrations between 1 to 5 ppm.

2012
Norliza Saparin | Zahariah Ismail | Mohd Suria Affandi Yusoff | Shawaluddin Tahiruddin
Refined, Bleached and Deodorized Palm Stearin (RBDPS) is a solid fraction obtained from Refined, Bleached and Deodorized Palm Oil after fractionation by crystallization at controlled temperature. Fractionated RBDPS was found to be enriched with C16 fatty acids,
lacking in trans fat and has a high melting point. The fractionated RBDPS produced had an iodine value of 13.1 gI2/100g, C16 content of 79.7% and melting point 60°C .These characteristics indicate fractionated RBDPS has potential as a rumen bypass fat as well as providing desirable carbon chain composition for good milk characteristics.
